I need to find the original library of my iPhotos

Question

Hi Terence,
by mistake i clicked on the "create new" project when iphoto opened. ive lost all pictures and videos fo my childrfen over the past two years. i do have copies on an external hard disk so i didnt panic, however when i imported back these, i have the pictures but the videos who show each a different capacity, when opening it gives a duration of zero, and when played the playing bar rolls from the beigning to the end of the vdeo in a second. worst thing is that i realized then that the same is found on the copies ive made, so i havent any correct version of these videos. my only hope is to find the original library of my iphotos and redirect it to it, but i cant seem to find it, even under the following path: macintosh hd-users-(my name)- pictures-iphoto library- masters, i only find 2013 then 12 (december)...nothing before
these are the vidoes of my two young childfen and its horrifying to have lost these videos of them growing up, please help me

Try downloading Find Any File
http://apps.tempel.org/FindAnyFile/
this is a search app that looks in places the Spotlight doesn't. Set it to search the machine for folder names like
Originals
Previews
and see what it finds. It will find the current Library that you have, so you're looking for these ina different location.
If it finds nothing then you're into File Recovery software like File Salvage - you can download a free trial and it will scan the disk for you and tell you with might be recoverable. Actual recovery will require that you purchase the app. There may be many files with the same or similar names. Always recover the largest file size.
There are other such apps. Search on Macupdate or the App Store
